Zooarchaeology of Ban Chiang and the rise of early farming communities in mainland Southeast Asia
Ban Chiang Archaeological Site, located on Thailand's Khorat Plateau, reveals a unique faunal record that contrasts sharply with coastal Southeast Asian sites. Excavations indicate that early farmers (ca. 1500 BC) introduced domesticated cattle, water buffaloes, pigs, and dogs from southern China, integrating them into an economy that also relied on hunting, fishing, and shellfish gathering. Notably, jungle fowl (Gallus gallus) may have been locally domesticated. Unlike coastal sites where pigs and dogs dominated, Ban Chiang's inland environment shows a strong presence of domestic cattle and chickens. Recent research highlights an agricultural revolution (ca. AD 200) involving animal traction and plowing in the drier Mun River Valley, which facilitated early state formation. However, this shift appears muted or absent at Ban Chiang due to its higher natural rainfall, suggesting regional variability in the transition to complex societies.
Ban Chiang, Northeast Thailand, vol. 2C: The Metal Remains in Regional Context ed. by Joyce C. White and Elizabeth G. Hamilton
A comprehensive analysis of metal remains from Ban Chiang, Northeast Thailand, reveals that regional economic networks during the late second to first millennia BCE were community-based and nonhierarchical. The study, which includes contributions from multiple scholars, challenges previous assumptions about the Phu Lon production signature by demonstrating that prehistoric sites sourced metals from diverse networks, including Sepon in Laos, which was likely a primary copper source for Ban Chiang as early as 1000 BCE. Using geochemical characterization and lead isotopic analyses, researchers found that while metal production techniques varied regionally—with Central Thailand focusing on copper and Northeast Thailand on tin bronze—the casting traditions shared similarities, such as the use of lagged spouted crucibles and metalworking hearths. This synthesis contextualizes metal production within broader social growth and interaction patterns in Southeast Asia.
